Target Background

Function
Catalytic subunit of the DNA primase complex and component of the DNA polymerase alpha complex (also known as the alpha DNA polymerase-primase complex - primosome/replisome) which play an essential role in the initiation of DNA synthesis. During the S phase of the cell cycle, the DNA polymerase alpha complex (composed of a catalytic subunit POLA1, an accessory subunit POLA2 and two primase subunits, the catalytic subunit PRIM1 and the regulatory subunit PRIM2) is recruited to DNA at the replicative forks via direct interactions with MCM10 and WDHD1. The primase subunit of the polymerase alpha complex initiates DNA synthesis by oligomerising short RNA primers on both leading and lagging strands. These primers are initially extended by the polymerase alpha catalytic subunit and subsequently transferred to polymerase delta and polymerase epsilon for processive synthesis on the lagging and leading strand, respectively. In the primase complex, both subunits are necessary for the initial di-nucleotide formation, but the extension of the primer depends only on the catalytic subunit. Synthesizes 9-mer RNA primers (also known as the 'unit length' RNA primers). Incorporates only ribonucleotides in the presence of ribo- and deoxy-nucleotide triphosphates (rNTPs, dNTPs). Requires template thymine or cytidine to start the RNA primer synthesis, with an adenine or guanine at its 5'-end. Binds single stranded DNA.
Gene References into Functions
  1. No mutations within PRIM1 were found in Chinese women with primary ovarian insufficiency. PMID: 27599756
  2. Data suggest that PRIM1-p58,C-terminal domain stays bound to initiating NTP and 3prime-overhang DNA during whole cycle of RNA primer synthesis; meanwhile, PRIM1-p49 slides along DNA template toward 5prime-end with PRIM1-p58,N-terminal domain attached. PMID: 26710848
  3. Data indicate that the conformational changes in primase are necessary to accomplish the initiation and then elongation of RNA synthesis. PMID: 25550159
  4. Findings indicate that tethering of DNA primase Prim1 to the replisome by DNA polymerase alpha (pol alpha) is critical for the normal action of DNA replication forks in eukaryotic cells. PMID: 22593576
  5. Mechanisms by which human DNA primase chooses to polymerize a nucleoside triphosphate PMID: 20030400
